Recommendations

Block external access at the network boundary, unless external parties require service.

Filter access to the affected computer at the network boundary if global access isn't needed. Restricting access to only trusted computers and networks might greatly reduce the likelihood of a successful exploit.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.

Use NIDS to detect suspicious or anomalous network traffic. Monitor logs for signs of malicious activity.

Implement multiple redundant layers of security.

Memory-protection schemes such as nonexecutable stack and heap configurations and randomly mapped memory segments will complicate exploits of memory-corruption vulnerabilities.
